Decommissioning And Disposal; Decommissioning - Siemens SIMOTICS T-1FW6 Operating Instructions Manual

Decommissioning and disposal

Risk of death and crushing as a result of permanent magnet fields
Severe injury and material damage can result if you do not take into consideration the safety
instructions relating to permanent magnet fields.
• Refer to Chapter "Danger from strong magnetic fields (Page 28)".
10.1

Decommissioning

Sequence when decommissioning and disassembling the motor
Risk of injury and material damage
Injury and/or destruction of motor components can occur if you do not observe the specified
sequence when decommissioning and disassembling the motor.
• Perform decommissioning and disassembly work in the specified sequence only.
Procedure
1. Bring the motor into a no-voltage condition. Wait until the DC link of the power module has
been discharged.
2. Allow the motor to cool down for at least 30 min.
3. Switch off the cooling. Reduce the pressure to 0 bar.
4. Disconnect the power and signal cables and the coolant pipes.
5. Insulate the open power connections.
6. Drain the coolant from the motor and dispose of it correctly.
7. Remove chips, dirt, foreign particles, etc. from the motor.
8. Insert the spacer film between the stator and rotor so that the stator and rotor cannot touch
each other. If the stator and rotor come into contact with each other, these two components
can be separated again only with considerable effort. The reason for this is the extremely high
magnetic attractive forces which they exert.
9. Detach the flange surface of the rotor from the machine construction.
10. Pack the rotor in its original packaging and keep the spacer film.
